PUMP.

SPECIFICATION forming part. of Letters Patent No. 379,237, lated March 13, 1888.

Applcati-n filed hl'ayQ3,1887. Serial No. 939,088. (No model.)

To all whom, it 777,701/ concern.'

Be it known that I, WILUAM BAKER Mo- GINNIs, a citizen of the United States, residing` at Nevada, in the county of Vernon and Slate of Missouri, have invented certain new and useful Improvements in Pumps, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure l is a perspective view of the pump embodying my improvements. tical section.

A is a standard, the base A of which is adapted to be bolted to a flooring, and thus support the pump in proper working position.

The barrel B of the pump is iirmly mounted within the upright part A of the standard and connects with the horizontal arms of a hollow frame-work,which is made in rectangular form of sections, a a b b c c, of gas-pipe mounted by suitable elbow-couplings, el d, in one of which is screwed an ordinary petcock, f. This hollow framework or air-chamber has a central hollow tube, C, preferably of gas-pipe, and connected at its lower end to the gas-pipe sec` tions a a by means of a suitable T-coupling, D. This coupling D is of an ordinary wellknown form, except that it is provided upon one side with a short tube section or nipple, g, to receive a discharge-pipe, G; or, when preferred, this discharge-pipe may be connected with the air-chamber by means of an ordinary T-coupling arranged at either g or g2. The two gas-pipe sections c c are united to a T- coupling, H, which also receives the upper end of the central tube of pipe C.

h is a stuffing-box of any usual or approved construction, applied to the upper arm or leg of the T-coupling H, and through this stuft'- ing-boX passes the upper end of the pumprod B.

I is a cross-head attached to the upper end of the pump-rod by a T-coupling, il, to which it is secured firmly but adjustably by a setscrew, i. The cross-head passes through the T-coupling and can rock or oscillate therein.

I I are legs or arms or links projecting downward from the ends of the cross-head; or they may be made in one piece with the crosshead and bent into the proper shape after the -bar has been thrust through the tubular hole in the T-coupling.

Fig. 2 is a ver- .IK K is a bifurcatcd le\'er,ol' which the part J carries at its inner end a T-sha'ped coupling, in the outer ends of which are screwed two short pipe-sections with elbows k L, in which the pi pe-sections K K are screwed. rIhe lower ends of the arms or links I I are attached to the nearer endof the pipe-sections K K. These pipe -sections are Vfulcrumed about midway between their ends, and for this pugpose I pass them through T-pieces L, screwed onto the ends ot" either a horizontal pipe-section or nipples, which are supported in a T-piece, M, ar-

ranged between the pipe-section C and one of the side pieces of the air-chamber. In prac- 'tice I- prefer to support this fulcrum by means ofT-pieces N N, surrounding the respective pipe-sections-b c and connected therewith by set-screws or their equivalents, whereby the fulcrum is capable of vertical adjustment. In some cases I propose to connect the inner ends of the bifurcated lever adjustably with the legs or arms I I; but the fulcrnm need not necessarily be adjustable, in which case the T-pieces N N may be screwed to and form practically integral parts ofthe pipe-sections. Of course the T-picce through which these pipe-sections K K pass must fit the threaded ends of their separate pipe-sections or nipples somewhat loosely, so that they will turn thereon without undue friction.

m m are set-screws by means of which the pipe-sections K K can be fixed in their positions relatively to the fulcrum, and the use of these set-screws enables me to adjust the leverage by changing the position of the'lever relatively to this fulcrum.

Instead of connecting the inner ends of the lever directly to the cross-head by means of two links, one on either side, I may connect each end of the cross-head to one end of a lever, O, fulcrumed centrally upon the frame, and connect the opposite end of each of these levers to the inner end of one of the pipe-sections K K by means ofthe linko. Instead of or in addition to the standard A A', I may provide each sidepiece of the air-chamber with a foot-piece, asindicated in dotted lines at P P, such construction being a good one when it is desired to place the working-barrel of the pump some distance down in deep wells.

Y What I claim is- 1. napump,the combination,with the Working-barrel, of the rectangular frame having a vertical tube, C, a vertical tube, a, and bottom and top horizontal tube-sections, b c, said tubesections a, b, c, and C forming a substantially continuous chamber adapted to hold air in the parts a c C above the waterexit, and the piston-rod situated in the tube C, substantially as described.

2. The combination of the tubular frame having a vertical tubesection joined by the top and bottom horizontal tubes, the tube-sec'- tions C,joined air-tight to the top and bottom horizontal tubes by the couplings D H, and the piston-rod situated in the central tube, C, and passing through the said coupling D, substantially as set forth.

3. The combination, with the pump-tube C and the vertical tube a, parallel with and oom- Inunicating with the said tube C, of the fulcrum M, the tubular supports N therefor, vertically adjustable ou the tubes C a, the handle, the connecting-tubes K K, one on each side of the tubes C a, and both pivotally connected with the adjustable fulcrum M, substantially as set forth.

4. The combination, with the pumptube C and the tube a, parallel with and connected to the pump-tube C, of the fulcrurn M, the supports N N therefor, connected to the tubes b c, the handle, and the tubes K K, one on each side of the tubes C a, and both ad] ustably and pivotally connected to said fulcrum M, substantially as set forth.

In testimony whereof I affix my signature in 3 5 presence of two Witnesses.
